WILLIAM ANDLIER, OF CHICAGO, ILLINOIS.

DOOR CONSTRUCTION.

Application filed April 2, 1923.

To all whom it may concern:

Be it known that I, lVILLIAM ANDLER, a citizen of the United States, anda resident of the city of Chicago, county of Cook, and State ofIllinois, have invented certain new and useful Improvements in DoorConstructions, of which the following is a specification.

My invention relates to improvements in door constructions and has forits object the provision of means for preventing warping of doors orstraightening the doors after such warping has occurred.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification, and in which,

Fig. l is a face view of adoor construction embodying the invention;

Fig. 2, an end View of the same;

Fig. 3, a detail View shown partially in section, of an attachmentemployed in the construction Fig. l, a view similar to Fig. 1, butshowing a modified form of construction; and

Fig. 5, an enlarged section taken on line 5-4) of Fig. 4E.

The form of construction illustrated in Figs. 1, 2 and 3 comprises anordinary door having a truss construction attached there- .0 adjacentthe free or swinging edge thereof. This truss construction comprisesthreaded rods 6 and 7, the rod 6 being threaded in a socket 9 on abracket 10 secured to the upper edge of the door and the rod 7 beingthreaded in a socket 11 on a bracket 12, projecting outwardly from thecentral portion of the door. The rods 6 and 7 are connected by a turnbuckle 8. Similar brackets 10 and 12 are also secured to the lowerportion of the door and connected by threaded rods 13 and a turn buckle8. A handle yoke 14 is secured to the brackets 12 in position to span orpass around the door knob 15.

By this arrangement a reinforcing truss Serial No. 629,304.

is provided on the side of the door which is expansible or contra-ctableto exert a thrust or pull on the door to straighten the same in case thedoor has become warped as frequently happens.

In the form of construction illustrated in F i gs. a and 5 a door isillustrated equipped with av handle 16 in addition to the usual knob 15and the connecting yoke 14- of the truss construction is omitted.Otherwise the construction is to all intents and purposes indenticalwith that already described. lVlrile I have illustrated and describedthe preferred form of construction for carrying my invention intoeffect, this is capable of variation and modification without departingfrom the spirit of the invention. I, therefore, do not wish to belimited to the precise details of construction set forth, but desire toavail myself of such variations and modifications as come within thescope of the appended claims.

Having described my invention what I claim as new and desire to secureby Letters Patent, is:

1. The combination with a door, of threaded socket members having meansfor attachment to the flat upper and lower portions thereof adjacent thefree edge of the door; brackets secured to the central portion of thedoor adjacent the free edge thereof and provided with threaded socketsaligned with said first mentioned sockets in a plane at an angle to theplane of the door; rods threaded in said sockets, and turn bucklesconnecting said rods, substantially as described.

2. The combination with a. door, of threaded socket members having meansfor attachment to the flat upper and lower portions thereof adjacent thefree edge of the door; brackets secured to the central portion of thedoor and provided with threaded sockets aligned with said firstmentioned sockets in a plane at an angle to the plane of the door; rodsthreaded in said sockets; turn buckles connecting said rods; and meansconnecting said central bracket-s, substantially as described.
